Dilution by weight of ZEP520A vs spin speed from 1000 to 6000 rpm was generated in previous work. The aim is to provide an approximate clearing and base dose for the ZEP520A standard process at the Singh Center for Nanotechnology.ZEP520Acontrast curveo-xyleneroom temperatureclearing dosebase doseNanoscience and NanotechnologyReport
